ABSTRACT

Herbicidally active haloalkyl-substituted 3-(4,5-dihydroisoxazol-3-yl)benzoylcyclohexenones of the formula Iin which R1 to R3 and R5 to R14 are as defined in the description and R4 is C1-C4-haloalkyl are described.

The present invention relates to haloalkyl-substituted 3-(4,5-dihydroisoxazol-3-yl)benzoylcyclohexenones and to processes for their preparation, to compositions comprising them and to the use of these derivatives or compositions for controlling harmful plants.

WO 96/26200 discloses herbicidal 2-benzoylcyclohexane-1,3-diones.

The haloalkyl-substituted 3-(4,5-dihydroisoxazol-3-yl)benzoylcyclohexenones of the formula I can be obtained by different routes, for example by the processes below.

Process A:

Compounds of the formula I where R⁸=OH are obtained by reacting compounds of the formula II with an activated benzoic acid derivative IIIα or a benzoic acid IIIβ, which is preferably activated in situ, to give the corresponding acylation product I′ and subsequent rearrangement.

L¹ is hydroxyl or a nucleophilically displaceable leaving group, such as halogen, for example bromine or chlorine, hetaryl, for example imidazolyl or pyridyl, carboxylate, for example acetate, trifluoroacetate, etc.

The activated benzoic acid IIIα can be employed directly, such as in the case of the benzoyl halides, or be generated in situ, for example using dicyclohexylcarbodiimide, triphenylphosphine/azodicarboxylic ester, 2-pyridine disulfide/triphenylphosphine, carbonyldiimidazole, etc.

It may be advantageous to carry out the acylation reaction in the presence of a base. The reactants and the auxiliary base are in this case advantageously employed in equimolar amounts. A slight excess of auxiliary base, for example from 1.2 to 1.5 molar equivalents, based on II, may be advantageous in certain cases.

Suitable auxiliary bases are tertiary alkylamines, pyridine or alkali metal carbonates. Suitable for use as solvents are, for example, chlorinated hydrocarbons, such as methylene chloride, 1,2-dichloroethane, aromatic hydrocarbons, such as toluene, xylene, chlorobenzene, ethers, such as diethyl ether, methyl tert-butyl ether, dimethoxyethane, tetrahydrofuran, dioxane, polar aprotic solvents, such as acetonitrile, dimethylformamide, dimethyl sulfoxide, or esters, such as ethyl acetate or mixtures of these.

If the activated carboxylic acid component used is a benzoyl halide, it may be advantageous to cool the reaction mixture to 0-100° C. when adding this reaction partner. The mixture is subsequently stirred at 20-100° C., preferably at 25-50° C., until the reaction has ended. Work-up is carried out in a customary manner, for example by pouring the reaction mixture into water and extracting the product of value. Solvents which are particularly suitable for this purpose are methylene chloride, diethyl ether, dimethoxyethane and ethyl acetate. The organic phase is dried and the solvent is removed, after which the crude ester I′ can be employed for the rearrangement without any further purification.

The rearrangement of the esters I′ to the compounds of the formula I is advantageously carried out at 20-40° C. in a solvent and in the presence of a base and, if appropriate, using a cyano compound as catalyst.

Suitable solvents are, for example, acetonitrile, methylene chloride, 1,2-dichloroethane, dioxane, ethyl acetate, dimethoxyethane, tetrahydrofuran, toluene or mixtures of these. Preferred solvents are acetonitrile and dioxane.

Suitable bases are tertiary amines, such as triethylamine, pyridine or alkali metal carbonates, such as sodium carbonate or potassium carbonate, which are preferably employed in an equimolar amount or an up to four-fold excess, based on the ester. Preference is given to using triethylamine or alkali metal carbonates, preferably in twice the equimolar amount, based on the ester.

Suitable cyano compounds are inorganic cyanides, such as sodium cyanide and potassium cyanide, and organic cyano compounds, such as acetone cyanohydrin and trimethylsilyl cyanide. They are employed in an amount of from 1 to 50 mol percent, based on the ester. Preference is given to using acetone cyanohydrin or trimethylsilyl cyanide, for example in an amount of from 5 to 15, preferably 10, mol percent, based on the ester (examples of cyanide-catalyzed rearrangements of enol esters of cyclohexane-1,3-diones are mentioned, for example, in EP-A 186 118 and U.S. Pat. No. 4,780,127).

Work-up can be carried out in a manner known per se. The reaction mixture is, for example, acidified with dilute mineral acid, such as 5% strength hydrochloric acid or sulfuric acid, and extracted with an organic solvent, for example methylene chloride or ethyl acetate. The organic extract can be extracted with 5-10% strength alkali metal carbonate solution, for example sodium carbonate or potassium carbonate solution. The aqueous phase is acidified and the resulting precipitate is filtered off with suction and/or extracted with methylene chloride or ethyl acetate, and the mixture is dried and concentrated.

The cyclohexenones of the formula II are known or can be prepared by processes known per se (for example EP-A 71 707, EP-A 142 741, EP-A 243 313, U.S. Pat. No. 4,249,937, WO 92/13821).

The compounds of the formula IIIβ can be obtained, for example, as follows:

L² is a leaving group, such as halogen, for example chlorine, bromine or iodine, or sulfonate, such as mesylate or triflate; preference is given to bromine or triflate.

The 4,5-dihydroisoxazol-3-ylbenzene derivatives V can be obtained, for example, by converting oximes of the formula IV in a manner known per se via the hydroxamic acid chloride intermediates. The latter are used to generate, in situ, nitrile oxides which react with alkenes to form the desired products (cf., for example, Chem. Ber. 106 (1972), 3258-3274).

The 4,5-dihydroisoxazol-3-ylbenzene derivative V is then reacted with carbon monoxide and water in the presence of a catalyst and of a base to give IIIβ.

Suitable catalysts are palladium-ligand complexes in which the palladium is present in oxidation state 0, metallic palladium, which has optionally been absorbed on a support, and preferably palladium(II) salts. The reaction with palladium(II) salts and metallic palladium is preferably carried out in the presence of complex ligands.

An example of a suitable palladium(0)-ligand complex is tetrakis(triphenylphosphine)palladium.

Metallic palladium is preferably absorbed on an inert support such as, for example, activated carbon, silica, alumina, barium sulfate or calcium carbonate. The reaction is preferably carried out in the presence of complex ligands such as, for example, triphenylphosphine.

Examples of suitable palladium(II) salts are palladium acetate and palladium chloride. The presence of complex ligands such as, for example, triphenylphosphine is preferred.

Suitable complex ligands for the palladium-ligand complexes, or in whose presence the reaction with metallic palladium or palladium(II) salts is preferably carried out, are tertiary phosphines whose structure is represented by the following formulae:

where z is 1 to 4 and the radicals R^(a) to R^(g) are C₁-C₆-alkyl, C₃-C₆-cycloalkyl, aryl-C₁-C₂-alkyl or, preferably, aryl. Aryl is, for example, naphthyl and unsubstituted or substituted phenyl such as, for example, 2-tolyl and, in particular, unsubstituted phenyl.

The complex palladium salts can be prepared in a manner known per se starting from commercially available palladium salts such as palladium chloride or palladium acetate and the appropriate phosphines, such as, for example, triphenylphosphine or 1,2-bis(diphenylphosphino)ethane. Many of the complexed palladium salts are also commercially available. Preferred palladium salts are [(R)(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl]-palladium(II) chloride, bis(triphenylphosphine)palladium(II) acetate and, in particular, bis(triphenylphosphine)palladium(II) chloride.

The palladium catalyst is usually employed in a concentration of from 0.05 to 5 mol %, and preferably 1 to 3 mol %.

Suitable bases are tertiary amines, such as, for example, N-methylpiperidine, ethyldiisopropylamine, 1,8-bisdimethylaminonaphthalene or, in particular triethylamine. Also suitable is alkali metal carbonate, such as sodium carbonate or potassium carbonate. However, mixtures of potassium carbonate and triethylamine are also suitable.

In general, from 2 to 4 molar equivalents, in particular 2 molar equivalents, of the alkali metal carbonate, and from 1 to 4 molar equivalents, in particular 2 molar equivalents, of the tertiary amine are employed, based on the 4,5-dihydroisoxazol-3-ylbenzene derivative of the formula V.

Particular preference is given to ethers, such as 1,4-dioxane and dimethoxyethane.

It is also possible to obtain the compounds of the formula IIIα (L¹=OH) by converting an oxime of the formula VI into the corresponding hydroxamic acid halide, in particular hydroxamic acid chloride, generating, in situ, a nitrile oxide and reacting this with an alkene (cf., for example, Chem. Ber. 106 (1973), 3258-3274). The ester VII is then hydrolyzed under conditions known per se to give the compounds of the formula III where L¹=hydroxyl.

L³ is a C₁-C₆-alkoxy radical.

Compounds of the formula I where R⁸=OR¹⁵ and SR¹⁵ are obtained by reacting compounds of the formula I where R⁸=hydroxyl and mercapto, respectively, with alkylating agents, carbamoylating agents or acylating agents L⁴-R¹⁵ (IV).

L⁴ is a nucleophilically displaceable leaving group, such as halogen, for example bromine or chlorine, acyloxy, for example acetyloxy or ethylcarbonyloxy, or alkylsulfonyloxy, for example methylsulfonyloxy or trifluoromethylsulfonyloxy.

The starting materials are generally employed in equimolar amounts. However, it may also be advantageous to employ an excess of one or the other component.

PREPARATION EXAMPLES 2-Methyl-3-(5-chloromethyl-4,5-dihydroisoxazol-3-yl)-4-methyl-sulfonylbenzoyl Chloride

3.23 g (27.2 mmol) of thionyl chloride were added dropwise to a mixture of 4.5 g (13.6 mmol) of 2-methyl-3-(5-chloromethyl-4,5-dihydroisoxazol-3-yl)-4-methyl-sulfonylbenzoic acid, 100 ml of toluene and three drops of N,N-dimethylformamide. The mixture was refluxed for 4 hours and then cooled, and the solvent was removed. The residue was then taken up in methylene chloride and once more concentrated to dryness. This gave 4.74 g (100% of theory) of the title compound in the form of a pale powder.

3-[2-Methyl-3-(5-chloromethyl-4,5-dihydroisoxazol-3-yl)-4-methyl-sulfonylbenzoyl]bicyclo[3.2.1]octane-2,4-dione (Compound 2.2)

Under nitrogen and at 0-5° C., 0.7 g (2 mmol) of 2-methyl-3-(5-chloromethyl-4,5-dihydroisoxazol-3-yl)-4-methyl-sulfonylbenzoyl chloride in 40 ml of acetonitrile was added dropwise to 0.28 g (2 mmol) of bicyclo[3.2.1]octane-2,4-dione and 0.4 g (4 mmol) of triethylamine in 40 ml of acetonitrile, and the mixture was stirred at room temperature for 4 hours. 1 drop of trimethylsilyl cyanide and 0.05 g of potassium carbonate were then added, and the mixture was stirred at 40° C. for 2 hours and then at room temperature for 12 hours. Following this, the solvent was removed, the residue was taken up in ethyl acetate and the solution was extracted repeatedly with 5% strength potassium carbonate solution. The combined extracts were then adjusted to pH 2-3 using 10% strength hydrochloric acid and extracted repeatedly with methylene chloride. These combined organic extracts were then washed with water and dried, and the solvent was removed. The oily yellow residue was chromatographed over silica gel (mobile phase: methylene chloride/methanol=99/1 to 97/3). This gave 0.4 g (44% of theory) of the title compound of melting point 98-103° C.

If the active compounds are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spraying equipment, in such a way that they come into contact as little as possible, if at all, with the leaves of the sensitive crop plants, while the active compounds reach the leaves of undesirable plants growing underneath, or the bare soil surface (post-directed, lay-by).

The application rates of the compound of the formula I are from 0.001 to 3.0, preferably from 0.01 to 1.0 kg/ha of active substance (a.s.), depending on the control target, the season, the target plants and the growth stage.

To widen the activity spectrum and to achieve synergistic effects, the haloalkyl-substituted 3-(4,5-dihydroisoxazol-3-yl)benzoylcyclohexenones of the formula I may be mixed with a large number of representatives of other herbicidal or growth-regulating active compound groups and then applied concomitantly. Suitable components for mixtures are, for example, 1,2,4-thiadiazoles, 1,3,4-thiadiazoles, amides, aminophosphoric acid and its derivatives, aminotriazoles, anilides, (het)aryloxyalkanoic acids and their derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-(hetaroyl/aroyl)-1,3-cyclohexandiones, hetaryl-aryl ketones, benzylisoxazolidinones, meta-CF₃-phenyl derivatives, carbamates, quinolinecarboxylic acid and its derivatives, chloroacetanilides, cyclohexenone oxime ether derivatives, diazines, dichloropropionic acid and its derivatives, dihydrobenzofurans, dihydrofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl ether, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phenyl-3,4,5,6-tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- and hetaryloxyphenoxypropionic esters, phenylacetic acid and their derivatives, 2-phenylpropionic acid and its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers, sulfonamides, sulfonylureas, triazines, triazinones, triazolinones, triazolecarboxamides and uracils.

It may furthermore be advantageous to apply the compounds of the formula I, alone or else concomitantly in combination with other herbicides, or in the form of a mixture with other crop protection agents, for example together with agents for controlling pests or phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions, which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.

USE EXAMPLES

The herbicidal activity of the haloalkyl-substituted 3-(4,5-dihydroisoxazol-3-yl)benzoylcyclohexenones of the formula I was demonstrated by the following greenhouse experiments:

The cultivation containers used were plastic pots containing loamy sand with approximately 3.0% of humus as the substrate. The seeds of the test plants were sown separately for each species.

For the pre-emergence treatment, directly after sewing the active compounds, which had been suspended or emulsified in water, were applied by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transparent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants, unless this was adversely affected by the active compounds.

For the post-emergence treatment, the test plants were first grown to a height of from 3 to 15 cm, depending on the plant habit, and only then treated with the active compounds which had been suspended or emulsified in water. The test plants were for this purpose either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment. The application rate for the post-emergence treatment was 0.25 or 0.125 kg of a.s. (active substance)/ha.

Depending on the species, the plants were kept at 10-25° C. or 20-35° C. The test period extended over from 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

The evaluation was carried out using a scale from 0 to 100. 100 means no emergence of the plants, or complete destruction of at least the aerial parts and 0 means no damage, or normal course of growth.

The plants used in the greenhouse experiments were of the following species:

Scientific name Common name Abutilon theophrasti velvet leaf Avena fatua wild oat Brachiaria plantaginea alexandergrass Chenopodium album lambsquaters Polygonum persicaria ladysthumb Setaria faberi giant foxtail

At application rates of 0.25 or 0.125 kg/ha, the compound 2.1 (Table 2) showed very good post-emergence action against the abovementioned undesirable plants.
